California Seller’s Property Questionnaire (SPQ): Hidden Risks Exposed
Learn California SPQ requirements and avoid hidden risks.
California SPQ: Uncover Hidden Property Risks Before Buying
Imagine closing on your dream home in California, only to discover months later that the foundation is cracking due to undisclosed soil issues, costing you tens of thousands in repairs. This nightmare scenario happens more often than you'd think—according to National Association of Realtors (NAR) reports, up to 94% of homebuyers overlook critical risks in disclosure documents during the excitement of the purchase. The California Seller’s Property Questionnaire (SPQ) is a key document designed to reveal these hidden dangers, but its dense questions and legalese can easily lead to missed red flags.
In California's competitive real estate market, sellers are legally obligated to disclose material facts that could affect a property's value or desirability, as outlined in California Civil Code §1102. But the SPQ goes deeper, probing into specifics like structural defects, environmental hazards, and neighborhood nuisances. Failure to spot issues here can result in legal battles, with average undisclosed problems costing buyers around $18,000, based on IonDocs' analysis of over 2,847 properties per month.
That's where IonDocs comes in. Our AI-powered platform analyzes your SPQ and entire disclosure package in just 60 seconds, translating complex details into plain English, assigning a risk score, and highlighting negotiation points. Whether it's a $15K+ HOA assessment or lurking structural problems, we empower homebuyers to make informed decisions.

What is the California Seller’s Property Questionnaire (SPQ)?
The California Seller’s Property Questionnaire (SPQ) is a supplemental disclosure form provided by the California Association of Realtors (C.A.R.), designed to give buyers a more detailed understanding of potential issues affecting a property's condition, value, or desirability. Unlike the mandatory Real Estate Transfer Disclosure Statement (TDS) required under California Civil Code §1102.6, the SPQ is not legally required in all transactions but is commonly used to ensure comprehensive disclosures and reduce liability for sellers.
Sellers must complete the SPQ based on their actual knowledge, answering yes/no questions across various categories. It supplements the TDS by delving into specifics that might not be covered elsewhere, such as past repairs, environmental concerns, or neighborhood problems. Per C.A.R. guidelines and state real estate commission forms, the SPQ helps fulfill the seller's duty to disclose material facts, as emphasized in cases like Lingsch v. Savage (1963), where nondisclosure led to buyer lawsuits.
Who must provide it? The seller, typically with assistance from their real estate agent, provides the SPQ to the buyer during the escrow period. Buyers receive it as part of the disclosure package. It's required in most residential transactions involving single-family homes, condos, or multi-unit properties up to four units, especially when the seller is not exempt from TDS (e.g., probate sales or transfers between family members).
The SPQ is typically delivered within seven days of contract ratification, as per standard C.A.R. purchase agreements. Failure to provide accurate disclosures can lead to penalties from the California Department of Justice or civil lawsuits, with fines up to $10,000 in severe cases of fraud.

Key Sections Buyers Must Review
The SPQ is a multi-page form with yes/no questions organized into sections. Buyers should scrutinize these for any "yes" answers, which require explanations from the seller. Always verify legal claims with a professional attorney or inspector, as IonDocs flags potential issues but recommends human review for complex matters.
Section 5: Statutorily or Contractually Required or Related – Covers legal disclosures like deaths on the property within the last three years, methamphetamine contamination orders, industrial zoning proximity, insurance claims in the past five years, and other material defects. (Reference: CA Civil Code §1710.2 for death disclosures.)
Section 7: Structural, Systems and Appliances – Details defects in heating, plumbing, electrical systems, roof, foundation, or appliances; leased systems like solar panels; or alternative septic systems. These can signal costly repairs—verify with a home inspection.
Section 9: Water-Related and Mold Issues – Addresses water intrusion, leaks, flooding, high water tables, or mold infestations. Mold problems, common in California's humid coastal areas, may require professional remediation.
Section 10: Pets, Animals and Pests – Inquires about pet damage, wildlife issues, pest infestations, or past treatments. Termite damage, for instance, affects 1 in 5 California homes per state reports.
Section 11: Boundaries, Access and Property Use by Others – Discusses surveys, easements, encroachments, or unauthorized access. Boundary disputes can lead to legal fees; cross-check with a title report.
Section 14: Title, Ownership Liens, and Legal Claims – Reveals other title holders, leases, liens (e.g., PACE loans), or pending lawsuits. These could impact ownership—always consult a title expert.

Common Red Flags & Real Risks
IonDocs' data from analyzing thousands of properties reveals that overlooked SPQ disclosures often lead to significant financial burdens. Here are five common red flags, drawn from public court cases and NAR reports, with estimated impacts:
Structural Defects (e.g., Foundation or Roof Issues) – A "yes" in Section 7 might indicate settling soil or leaks. In Furla v. Jon Douglas Co. (1998), nondisclosure of foundation cracks cost the buyer $50,000 in repairs. Average fix: $10K–$30K.
Water Damage or Mold – Section 9 flags like past flooding can hide chronic issues. California DOJ data shows mold lawsuits rising 20% annually; remediation averages $15K, per IonDocs stats.
Pest Infestations – Termites or rodents in Section 10 are rampant. A Google Scholar-cited case, Loughrin v. Superior Court (1993), involved undisclosed pests leading to $20K damages.
Boundary or Easement Disputes – Section 11 revelations can uncover neighbor encroachments. In Ryan v. Real Estate of the Pacific (2019), failure to disclose easements resulted in a $25K settlement.
Environmental Hazards or Liens – Meth contamination (Section 5) or PACE liens (Section 14) pose health and financial risks. State legislature records note penalties up to $5K for nondisclosure, with cleanup costs exceeding $18K on average.
These risks aren't hypothetical—NAR reports show 15% of transactions face post-closing disputes. IonDocs identifies these in 60 seconds, helping buyers negotiate credits or walk away.
